I'm thinking about buying an iPad mini, and I was wondering if there is a way to hack it to use it as a phone? I know you can use skype/google phone/whatever over data/wifi and you can use the data from an existing phone plan, but can you get a jailbroken dialler app and headset and use your true blue minutes from another phone plan? Or would this require different hardware? I like iPhones but 1. they're too expensive and 2. the screens are too small... I'd like to be able to read a book off of it without having to change the page every two sentences! Any help appreciated, thanks.
